Not all babies have a four-month sleep regression. Research studies have shown that there is a considerable amount of individual variation in the sleep of babies. Some babies may not have detectable sleep regression at four months, while others may have difficulty sleeping at this age or at a point earlier or later. A popular theory suggests that young children go through exactly 10 difficult periods of restlessness followed by leaps in growth, but the evidence is not as clear.
But while experts (and parents) agree that sleep patterns can vary wildly during a baby's first two years, no rigorous data supports the idea that nap and nighttime changes occur at predetermined times or are related to specific developmental milestones. And it's hard to say whether an attack of irritability is due to a “regression of sleep” or simply because a baby is a baby. Exhausted parents who take comfort in thinking about their baby's next jump may be dreaming. In 1974, Robert Horwich, an animal researcher at the Chicago Zoological Society, noticed that several baby members of 12 different primate species from two Chicago zoos tended to change their lactation habits (sometimes by breastfeeding more, sometimes breastfeeding less) at about the same time as others.
He called the phases of intensified lactation “regressive periods,” defining them as a time during which babies returned to a level of need and attachment that they had previously overcome. More than a decade later, in the mid-80s, a research team of husband and wife psychologists from the Netherlands, Dr. were studying chimpanzees in Tanzania and noticed that these same periods occurred just before some chimpanzees left their mothers and began to take care of themselves independently. Each regression seemed to generate progress in its development shortly thereafter.
Van de Rijt published that study in the peer-reviewed Journal of Reproductive and Infant Psychology. That same year, they released their new book, “The Wonder Weeks,” which cataloged exactly when each of the 10 leaps would occur and the difficult behaviors and developmental milestones they would coincide with; and what activities parents should do with their babies to convince those skills to develop or help. feel safe as they explore in new ways. For example, if you want to help your baby feel secure in the midst of his attachment attack, shorter sleep periods, and the development of the senses in week 4 or 5, the book suggests that you curl him up, rock him, and sing to him.
At week 37, lack of sleep and need go hand in hand with baby's new ability to classify objects (such as toys, food, and clothing). At this time, “Wonder Weeks” suggests asking babies to identify and handle objects from specific groups, “pass the toy”, pass the food to help at this stage. Critics say that 15 participants and two direct observations are too small a set to base a theory on. “To make it convincing,” said Dr.
Jodi Mindell, Ph.D. And, Dr. Mindell added: “I think that means looking at thousands of babies. Dr.
If you find behavior in two individuals, he said, “then you already have proof that the phenomenon exists and is not due to luck or chance. In a video on the Wonder Weeks website, Dr. Plooij stated that subsequent investigations confirmed the timed jumps. In the early 2000s, researchers from universities in Spain, England and Sweden tried to replicate the 1992 results in three different studies involving a total of 66 babies.
Plooij argued that these studies produced similar findings to his own. But only the Spanish study was published in a peer-reviewed journal, the gold standard of scientific publishing. And while he claimed to have found specific periods of regression within the first 14 months of life, he did so using a less than rigorous combination of weekly questionnaires and regular check-ups in a total of 18 babies. Those figures are not substantial enough to support an entire hypothesis, said Dr.
The University of Groningen refused to renew Dr. Plooij, now 72, insisted that he left by choice and disputed Dr. De Weerth's account that he interfered with the publication of his work. The important question for parents, according to Dr.
Shalini Paruthi, M, D. Luke's Hospital in Chesterfield, Mo. When parents ask her what method they should use to help their babies sleep more, she emphasized consistency in her approach over a particular approach. Parents can always bathe their baby before bedtime, for example, or spend time curled up in a cozy chair with the lights dimmed.
Hops, similarly, try to discourage parents from changing routines too quickly out of frustration. Your advice? Stay firm in your routine. Why do babies have a 4-month sleep regression?. However, not all babies experience it.
For those who do, it may come a month or so sooner or later. Not all babies go through 4-month sleep regression, I have seen many babies overcome this phase of development with little disruption of their sleep. Her parents have respected the sleep needs of their babies from the start and have worked hard to establish healthy sleep habits from the start. But even if you're currently making your way through this difficult time, there are things you can do to get back on track.
My next post will cover some of the most successful tips for working on four-month sleep regression. The 12-month sleep regression is actually the same as the 11-month regression, although if your toddler starts is in the twelfth month, you may actually transition to just a nap earlier. I would like to offer you a free 15-minute telephone evaluation with an expert sleep consultant, which I think will be very useful for you. Some argue that sleep disturbances around this age do not last long enough to qualify as a true regression of sleep.
Sleep regressions are points on a baby's sleep radar where he wakes up most often during the night or has a harder time napping. As with most regressions of sleep, it seems to coincide with developmental changes, such as learning to stand up or crawl. When you sleep your baby, either at the beginning or in the middle of the night, make sure he is not completely asleep. Incorporate enough tummy time into games during the day so your baby won't be distracted when trying to get him to sleep or go back to sleep.
Sleep regressions usually last a few weeks at most, and can even be as short as a few days in some cases. Another hug sounds much better than closing your eyes and doing it themselves, especially if they haven't practiced the ability to fall asleep alone. It seems to me that the other important factor of this 4-month fiasco is that until now parents have been sleeping their baby with a pacifier, rocking it, breastfeeding it until it falls asleep or some similar technique in which the baby is helped on the path to falling sleep. We know how difficult a sleep regression can be at any age, and because 4-month sleep regression is the first experience many parents experience with sleep regressions, it can be even more overwhelming.
Around this time, babies begin to sleep more like adults and less like babies, so this “regression” is often like a springboard to more mature sleep patterns. If they tend to fall asleep in their arms (or other sleeping surface), you'll want to give them the time and opportunity to adjust to falling asleep in the preferred sleeping space. . .
